High Quality Content by WIKIPEDIA articles! Dweomer (pronounced "dway-OH-mair") is the fictional system of magic depicted in Katharine Kerr`s novels of Deverry. This system is described by Kerr as being rooted in "what we might call `British revival Rosicrucianism,`" from the late Victorian age to the 1920s, which itself drew from Renaissance Rosicrucianism. According to Kerr, the lines of influence in her fictional magical system trace back through this Renaissance "Christian Kaballah" via the Jewish Kaballah to Late Roman Gnosticism. (As an inside joke, some of Kerr`s characters refer to a scroll by a certain "pseudo-Iamblichos": there was a genuine Iamblichos writing (in Greek) in the late Roman world about magical topics.) There are also some similarities between Kerr`s dweomer and ideas found in Theosophy.
